Definitions

  • the invention relates to a push-button arrangement having a push-button switch which is arranged on a printed board and which may be actuated by means of a ram of a ram cap, the ram cap being held in a ram holder by means of spring catches, on which ram holder a compression spring which is pushed on to the ram is held, this spring holding the ram cap in an initial rest position, and the ram cap projecting into an opening of a switch strip.
  • Push-button arrangements of this kind are widely used in the control panel of household machines such as washing machines and dishwashers etc.
  • the switching lift is here very small and the operating fashion of the push-button switch is bistable, with the result that after each activation the push-button arrangement returns to its initial rest position.
  • the ram cap is led directly in the opening of the switch strip and serves at the same time as a push-button cap.
  • the size of the ram cap is determined by the spacing of the catch springs and the catch receiving means in the ram holder.
  • the switch strip therefore always has to be adapted to the ram caps of the push-button arrangements.
  • the object of the invention is so to design a push-button arrangement of the type mentioned initially that, despite the use of uniform ram caps and ram holders, the switch strip can be provided, independently of these, with openings and actuating ele of different sizes for the push-button arrangements.
  • This object is achieved according to the invention in that a push-button cap is placed on to the ram cap, which is led and held in the correspondingly enlarged or reduced opening of the switch strip so as to be adjustable, the switch strip having a guide bush directed towards the ram holder, and the push-button cover lying in the initial rest position with a stop web against the guide bush of the switch strip and surrounding the guide bush with a guide web.
  • the actuating element can be made larger or smaller. To this end, however, it is necessary to hold the push-button cover in the switch strip and to guide it adjustably. This is achieved through the holding sleeve of the switch strip as well as the stop web and the guide web of the push-button cover. Pushing back into the initial rest position is effected by the compression spring on the ram via the ram cap.
  • the adjustment path of the push-button cover is adapted to the actuating lift of the push-button switch.
  • the compression spring is pushed on to a holding sleeve of the ram holder, through which sleeve the ram is led.
  • the ram, the ram cap and the catch springs are formed as one piece.
  • the initial rest position of the ram cap is determined in that the catch springs are locked in to spaced-out catch receiving means of the ram holder and are held by means of moulded-on catch elements in the initial rest position.
  • the front side of the switch strip to be covered by means of a cover which is led with a covering sleeve into the opening of the switch strip, and in that the inner diameter of the covering sleeve and the outer diameter of the push-button cover are adapted to one another.
  • the necessary distinguishing marks are applied to the cover.
  • the guide bush of the switch strip on the outer side and the guide web of the push-button cover on the inner side to taper conically towards the free ends; it can then be easily adjusted when ush-button cover is actuated, but when it is returned to the initial rest position, however, it is centred in the opening of the switch strip or the covering sleeve of the cover. It is advantageous here if the convex face side of the ram cap has the same radius of curvature as the concave inner side of the push-button cover.
  • a bistable push-button switch 11 is fastened per push-button on to a printed board 10, this switch being activated by means of a ram 20.
  • Fig. 1 shows, in the initial position the ram cap 21, configured as one piece with the ram 20, is pressed by means of a compression spring 30 so far in the direction of the switch strip 14, arranged in front of same, until the catch elements 23 of the catch springs 22, moulded on to the ram cap 21, stop on the ram holder 12 arranged between the printed board 10 and the switch strip 14.
  • the catch springs 22 of the ram cap 21 are locked into catch receiving means 13 of the ram holder 12.
  • a holding sleeve 18 is moulded on to the side of the ram holder 12 facing the switch strip 14, on to which holding sleeve the compression spring 30 is pushed.
  • the ram 20 is led through this holding sleeve 18 and the compression spring 30 is supported on the ram holder 12 and the ram cap 21.
  • a pushbutton cover 25 which is adapted in diameter and which has been inserted from the rear side into the opening 29 of the switch strip 14.
  • a cover 16 with disishing marks can be attached, which projects with a covering sleeve 17 into the opening 29 of the switch strip 14.
  • the inner diameter of the covering sleeve 17 determines the outer diameter of the push-button cover 25.
  • the convex face side of the ram cap 21 has the same radius of curvature as the concave inner side of the push-button cover 25 with the result that a close fit is achieved.
  • the switch strip 14 has a guide bush aligned after the ram holder 12, whilst the push-button cover 25 passes on its free edge into a bearing web 27 aligned towards the outside a to a guide web 28 which follows on to the first web and is oriented towards the switch strip 14.
  • the push-button cover 25 is held in the initial rest position by the stopping of the bearing web 27 on the guide bush 15, through the action of the compression spring 30 and the ram cap 21.
  • the facing sides of the guide bush 15 and of the guide web 28 taper respectively towards their free ends, with the result that in the initial rest position the push-button cover 25 is centred in the covering sleeve 17 of the cover 16 and the opening 29 of the switch strip 14.
  • the switch strip 14, the cover 16 and the push-button cover 25 can therefore be laid out independently of the size of the ram cap 21 with the catch springs 22 and the spacing, determined by same, of the catch receiving means 13 in the ram holder 12.
  • the push-button cover 25 projects approximately by the switching lift of the push-button switch 11 on the cover, whilst in the switched position according to Fig. 2, the push-button cover 25 terminates approximately flush the cover 16.
  • the ram cap 21 is adjusted via the push-button cover 25.
  • the catch springs 22 are correspondingly adjusted in the catch receiving means 13 of the ram holder 12, the catch elements 23 lifting off the ram holder 12.
  • uide web 28 of the push-button cover 25 remains in the region of the guide bush 15, however has some play, with the result that no additional frictional loss occurs.
  • Compression spring 30 is tensioned more strongly, and thus, when the push-button switch 25 is released, the push-button arrangement is returned securely to its initial rest position according to Fig. 1.
  • the actuated centring of the push-button cover 25 is carried out via the guide web 28 sliding on to the guide bush 15.
